2.1 System connection diagram

2.2 Warning

 If the units demonstrate any problems, such as abnormal sound, smoke, heat from or

damage to power cables, disconnect the power plug from the outlet and contact your

sales representative.

If the power plug blades are distorted or discolored, do not use the unit

(Main unit, Battery charger)

 Uncoil the power cables before use, Do not bundle the cables during use, or fie with

nails. (Main unit, Battery charger)

 Do not pull on the cable. Hold the plug section and insert/remove it in a straight line,

damaged cables may result in electric shock, malfunction, or fire.

(Main unit, Battery charger)

 Do not place anything on the power cables. Do not route them under a rug or

furniture.

(Main unit, Battery charger)

 Do not cover the units with cloth or place them in locations with poor ventilation.

Doing so traps heat, and may result in electric shock or fire

 If you do not use the units for long periods of time, disconnect the power plugs from

the outlet

(Main unit, Battery charger)

 Do not disassemble the units. Touching the inside of the units may result in electric

shock

 Do not expose the units to any strong shock

 Do not exposé the units to direct sunlight, heat from heating appliances, high

temperatures, or dust

 Do not expose the units to high humidity or moisture

Water that accidentally enters the inside of the units may result in electric shock,

malfunction, or fire

 Do not touch the power cables or plugs with wet band

(Main unit, Battery charger)

 Main unit is a class I device. Be certain to connect to an AC outlet with a protective

grounding connection

 Main unit can be separated from the AC receptacle by turning off the unit by the front

power switch. In case of emergency, turn off this switch or unplug the power cable

from the AC receptacle

2.2.1 CAUTION on handling of the microphone unit

 Do not grasp the microphone to lift or pull on the microphone unit: pick up the unit by

its base

 Slowly bend and straighten the flexible part of the microphone. Do not bend it with

excessive force

 Do not drop the unit

 If you do not use the unit for long periods of time, remove the battery

 The dedicated lithium-ion battery should be used

 Do not cover the infrared section

 When the microphone units are too close together, high sound volume may cause

acoustic feedback, In this case, increase the space between the conference units or

turn down the volume

 After the battery has been removed and replaced, confirm that the power LED turns

off

2.2.2. CAUTION on installation

 After mounting the IR receiver units, be certain that they are securely fastened

 Do not install the IR receiver units or the microphone units near infrared-emitting

objects such as direct sunlight, incandescent lamps, halogen lamps, inverter

fluorescent lamps, or plasma displays

 Noise may be generated by interference regardless of the operating distance between

the IR receiver unit away from infrared-emitting objects

 Do not place any obstructions around the microphone units

2.2.3 CAUTION on battery charger handling

 If the charging terminal is dirty, poor contact will prevent the battery from being

charged properly. Periodically clean the charging terminals

 The battery charger may become hot during charging. Use it in a well-ventilated area

 After the battery is fully charged, turn off the battery charger or remove the batteries

2.2.4 CAUTION on battery handling (optional)

 The battery is dedicated to the microphone unit. Do not use it for other applications

 Use only the designated battery charger

 If the battery leaks and the liquid contacts your skin or clothing, immediately flush

with clean water

 If the battery leaks and the liquid contacts your eyes, immediately wash thoroughly

with clean water and seek medical assistance

 Do not throw the battery into fire or overheat it, Doing so may result in a fire

 Do not disassemble or modify the battery

 Do not short-circuit the + and – terminals with any metal or wire. Do not carry or

store the battery with metal products such as a necklace.

 If you discover battery leaks, discoloration, distortion, or the other problems, do not

use the battery

 Dispose of used batteries properly as industrial waste or contact our business office in

your neighborhood

2.2.5 CAUTION on handling the AC adapter (option)

 If the unit exhibits any problems, such as abnormal sounds and smoke, pull the power

plug from the outlet and contact your sales representative

 Do not pull on the cable. Hold the plug and insert/remove it in a straight line.

Damaged cables may result in electric shock, malfunction, or fire

 Do not cover the units with cloth. Doing so traps heat and may result in electric shock

or fire

 Do not handle the adapter with wet hands

 If you do you use the units for long periods of time, disconnect the power plugs from

the outlet

2.3 Identify room layout

2.3.1 Check coverage area

Real coverage area of conference room (usually coverage area of conference room is

smaller than the conference room area)

2.3.2 The relationship between ceiling height and infrared emitting and

receiving coverage area.

Note: The height mentioned about is the distance from ceiling to desk.

2.3.3 Check quantity of receiver unit

Please check the ceiling height and coverage area of one receiver unit with above

information (2.3.2), to make sure real coverage area can receive the signal well.

Calculate formula: (A: Receiver quantity, B: Real coverage area, C: Coverage area of one

receiver unit)

A≥B/C
